Loan modification is taking longer times, sometimes more than 2-3 months. Try the NACA's direct toll-free number 1-888-404-6222 or (510) 652-6622 since your location is in San Francisco.
If you have received the Notice of Default or trustee sale notice from your lender then let NACA know about this and ask what to do next in order to postpone the trustee sale. I hope they can help you to achieve what you want.
